9. Mounting and verifying the file systems 10. Setting and verifying the auto-mount parameters The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-x devices on the disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For further information on LVM configuration, see the HP-UX user documentation. HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure SCSI disk devices. See "Reference information for the HP System Administrator Manager SAM" on page 45 for further information. Verifying the device files and drivers The device files for new devices are usually created automatically during HP-UX startup. Each device must have a block-type device file in the /dev/dsk directory and a character-type device file in the /dev/rdsk directory. However, some HP-compatible systems do not create the device files automatically. If verification shows that the device files were not created, follow the instructions in "Creating the device files" on page 19. The following procedure verifies both types of device files: 1. Display the block-type device files in the /dev/dsk directory using the ls -l command with the output piped to more. Verify there is one block-type device file for each disk array device. Example # ls -l /dev/dsk | more Total 0 brw-r - - - - - 1 bin sys 28 0x006000 Dec 6 15:08 c6t0d0 brw-r - - - - - 1 bin sys 280 0x06100 Dec 6 15:08 c6t0d1 2. Verify that the block-type device file name for each device is correct. 3. Display the character-type device files in the /dev/rdsk directory using the ls -l command with the output piped to more. Verify that there is one character-type device file for each disk array device. Example # ls -l /dev/rdsk | more Total 0 crw-r - - - - - 1 bin sys 177 0x006000 Dec 6 15:08 c6t0d0 crw-r - - - - - 1 bin sys 177 0x006100 Dec 6 15:08 c6t0d1 4. Use the device data table you created to verify that the character-type device file name for each device is correct. This task can also be accomplished with the lssf command. 18 Installing and configuring HP-UX for the XP disk array

Mounting and verifying the file systems
10.
Setting and verifying the auto-mount parameters
The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-
x
devices on the
disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For
further information on LVM configuration, see the HP-UX user documentation.
HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure SCSI
disk devices. See
“
Reference information for the HP System Administrator Manager SAM
”
on page
45 for further information.
Verifying the device files and drivers
The device files for new devices are usually created automatically during HP-UX startup. Each device
must have a block-type device file in the
/dev/dsk
directory and a character-type device file in the
/dev/rdsk
directory.
However, some HP-compatible systems do not create the device files automatically. If verification
shows that the device files were not created, follow the instructions in
“
Creating the device files
”
on page 19.
The following procedure verifies both types of device files:
1.
Display the block-type device files in the
/dev/dsk
directory using the
ls
–
l
command with
the output piped to
more
. Verify there is one block-type device file for each disk array device.
Example
# ls
–
l /dev/dsk | more
Total 0
brw-r - - - - - 1 bin sys 28 0x006000 Dec 6 15:08 c6t0d0
brw-r - - - - - 1 bin sys 280 0x06100 Dec 6 15:08 c6t0d1
2.
Verify that the block-type device file name for each device is correct.
3.
Display the character-type device files in the
/dev/rdsk
directory using the
ls
–
l
command
with the output piped to
more
. Verify that there is one character-type device file for each disk
array device.
Example
# ls
–
l /dev/rdsk | more
Total 0
crw-r - - - - - 1 bin sys 177 0x006000 Dec 6 15:08 c6t0d0
crw-r - - - - - 1 bin sys 177 0x006100 Dec 6 15:08 c6t0d1
4.
Use the device data table you created to verify that the character-type device file name for each
device is correct.
This task can also be accomplished with the
lssf
command.
